Zach ThorpeTypes of synovial jointsHinge joints - These are found in the elbows and the knees. The name hinge joint is derived from the actual function as it works much a door hinge by connecting two or more bones to provide movement in two directions. Hinge joints work by either bending(flexing) or straightening (extending). This is seen in the knees as the hinge joint is connected to the quadriceps tendon to allow these movements. Ball and Socket joints - These joints are used primarily to connect two bones together but so they can literally move in any direction. The joint does this by providing the ability of Flexion, Extension, Adduction, Abduction and Rotation both internally and externally. An example of this would be the shoulder joint which allows your arm to move in any direction.Gliding - Gliding joints provide flat surfaces for bones so they can slide over each other in any direction. These are also known a plane joints due to them literally beinga flat surface for bones to glide across. Rotation can also occur in these joints however only slightly due to the shape of the surrounding bones and the elasticity the joint capsule.Condyloid - condyloid joints are egg shaped joints that are received into egg shaped cavities. This is so the joint can move in any type of angle as the actions of flexion, extension, adduction, abduction and circumduction can take place within this type of joint. An example of this type of joint would be between the wrist and the epiphysis ofthe Radius bone to allow the wrist to move in all directions.Saddle - Saddle joints are joints which provide movement in many different directions. Saddle joints are capable of Flexion, Extension, Adduction, Abduction andCircumduction and this is how they are able to provide many various directional movements. An example of this would be the where the wrist meets the thumb as they as they are both joined by saddle shaped synovial capsules.Pivot joints - Pivot joints are made up of two parts. One being a ring formed at the epiphysis of one bone and a rounded end at the epiphysis of another. These joints provide the movement of rotation of one bone around another bone and the most common example of this is where the cranium and vertebrae in the neck connects to the base of the skull to allow full rota
